How to make
Peel the watermelon and remove the seeds. You should have 1.1 lb (500 grams) of fruit in a cleaned state.
Peel and remove the seeds from the lemon, leaving them perfectly cleaned and free of the white part of the peel.
Cut the watermelon and citrus and place them in a blender. Add the sugar and crushed ice and blend at maximum speed for 1 minute or more, if necessary, depending on the capabilities of your appliance.
In tall glasses pour two fingers of baking soda and pour the fruit syrup on top. Dilute by pouring more soda and serve the lemonade immediately while the drink is cold and highly carbonated.
